The title compound, C 15 H 11 ClN 2 S, has been prepared by the reaction of Lawesson's reagent with N-(2-chlorobenzoyl)-N H -(4-methylbenzoyl)hydrazine, under microwave irradiation and in the absence of solvent. It crystallizes with two molecules per asymmetric unit and X-ray analysis reveals that t
